Fail to import domain when exec "java -jar"

[dangsg]

Describe the bug
This issue is happen when you wrap benerator-ce-3.1.0.jar into another jar, then execute with java -jar.
The root cause is that it cannot loadClass from inner jar file: spring-boot-test.jar -> benerator-ce.jar => com.rapiddweller.domain.address

To Reproduce
Steps to reproduce the behavior:

1. Create a spring boot project
2. Add benerator-ce 3.1.0 into pom.xml
3. Add a function with:

try (DescriptorRunner runner = new DescriptorRunner("benerator.xml", new DefaultBeneratorContext())) {
            runner.runWithoutShutdownHook();

4. mvn clean package: to build jar
5. java -jar target/file.jar to start spring boot server
6. Call an API to call function 3

Expected behavior
The behavior of "import" is very different from version 2.0.0 and 3.1.0. Need to take more time to check the different.
